Estimated Local Authority Level Greenhouse Gas (GHG) Emissions 2005 - current:
Southampton
1 What are we looking at?
The graphs that follow show the estimated greenhouse gas emissions for Southampton.
The graphs show territorial-based emissions: the emissions that come from activities carried out in the local authority.
The data used comes from the UK local authority and regional greenhouse gas emissions national statistics.
“These statistics provide the most reliable and consistent breakdown of greenhouse gas emissions across the country, using nationally available data sets going back to 2005. They cover territorial emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), although not fluorinated gases.”
See the guidance on using the data for more explanation.
2 Which are our biggest territorial emissions sources?
Figure 2.1: BEIS CO2e emissions by category

Figure 2.3 shows an interactive version of the same plot. Hovering over specific lines is useful for identifying the sources.

3 Which sources make up 50%, 75% or 95% of our territorial emissions?
We plot this for the first year in which we have data (2005).
Figure 3.1: Cumulative emissions by source
Now repeat this for the most recent year in which we have data (2021). Have they changed much?

4 How do our current territorial emissions compare with other local authorities?
This plot compares current emissions with the mean across all other local authorities in England.
Figure 4.1: Current emissions compared to mean emissions for all other local authorities
For comparison in 2021:
- Mean total territorial emissions in comparator local authorities = 394.5 T CO2e
- Southampton total territorial emissions = 274 T CO2e
